KVCompose: Efficient Structured KV Cache Compression with Composite Tokens
Large language models (LLMs) rely on key-value (KV) caches for efficient autoregressive decoding; however, cache size grows linearly with context length and model depth, becoming a major bottleneck in long-context inference. Prior KV cache compression methods either enforce rigid heuristics, disrupt tensor layouts with per-attention-head variability, or require specialized compute kernels. We propose a simple, yet effective, KV cache compression framework based on attention-guided, layer-adap…

Optimization of Base-n Radix Sort for Skewed Datasets
The importance and applications of sorting is apparent and needs no explanation. In this paper, we analyse a non-comparison sorting algorithm, Base-n Radix Sort (BNRS) and introduce an optimized vari- ant of BNRS, namely, Stable Logical Partition Radix Sort (SLPR). The complexity of these algorithms is measured by the input size $n$ and the maximum value $k$. We show that with respect to time complexity, these algorithms are more succinct than traditional comparison-based sorting algorithms for…

Dynamic polarization of nuclear spins by optically-oriented electrons and holes in lead halide perovskite semiconductors
A theory of dynamic polarization of the nuclear spin system via optically-oriented charge carriers in lead halide perovskites is developed and compared with the experiments performed on a FA$_{0.9}$Cs$_{0.1}$PbI$_{2.8}$Br$_{0.2}$ crystal. The spin Hamiltonians of the electron and hole hyperfine interaction with the nuclear spins of lead and halogen are derived. The hyperfine interaction of the halogen spins with charge carriers is shown to be anisotropic and depending on the position of the hal…
